You should post in this thread, where another TBG reader is daydreaming just like you are!!!

But seriously, the 4k 27" 144Hz G-Sync monitor is already here (well, at least in theory, in reality it's backordered likely forever...), the Z390 has been cancelled, the 9900K should be interesting but probably won't arrive by Q1'19, and the GeForce 1180 is going to be here far soonerr, likely September (for "release" purposes, but wide availability will be November).
